Hopefully some kind soul will help with a quick start and save us some time digging it out on our own

Subject: Using Flash Media Server and a single PC Server to do Live Streaming (not progressive download pre-recorded)...

... as opposed to one of the CDN services...

1 - Given an Intel i7 Quad Core PC with 12GB of ram... how many simultanious ~500kbs streams could one expect from the single PC?

2 - How much PC horspower must you really have to stream to...

25 simultanious viewers?

100 simultanious viewers?

1,000 simultanious viewers?

5,000 ?

3 - Does FMS install and run on a Windows 7 Pro machine or must you be running "server" software like IIS?

4 - What is the cost of FMSs vs FMS?

5 - If you are streaming your own content... not reselling streaming services... what does FMS cost?

Thanks for any help!

    Hi Will,

    As you wish to do a livestreaming using FMS, there are few stats that may help you:

    1. Limitation on the number of files served by FMS server are generally governed majorly by file bit-rate, your NIC available, your bandwidth, no. of clients/server, and also to some extent by protocol used (rtmp/rtmpt/rtmps/rtmpe, not very siginificant difference), file format (FLV/Mp4 etc). Lets say you have ~1000 files of ~500Kbps then NIC Bandwidth requirement to serve all of these files should be ~500Mbps, so a 1Gbps NIC card would do in that case. Also, there is an assumption that only 70% of an NIC can be exhausted to serve the clients.

    2. It has been observed that FMS consume around ~20% of cpu (quadcore Intel Xeon) while serving ~1000 clients, but note that it doesn't keep increasing linearly, so depending upon your hardware (Intel/AMD processor), it can perform even better for increasing number of clients as well.

    3. FMS has been exhaustively tested on Win2008 server and CentOS platforms, but we have seen that it also runs on Windows7 flawlessly (though not a certified platform). Use x64 version to avail the full benefit of 64-bit architecture.

    4. You can basically check the Adobe website for prices, as I checked it for same and found that FMSS was listed as $995 and FMIS was listed as $4500. You may like to go ahead and check the datasheet and feature sheet available there for more info.

    5. I dont think if there is any difference whether you like to use it for personal usage or for providing some hosted services, but you can cross-check with Adobe Support and they can tell you better in my opinion,
